Endurance Technologies, Inc. formerly known as Epoxical, Inc. is a manufacturer in Applications Bonding Casting, Cold Molding, Core Bonding, Fairing Flame Retardant High Temperature Infusion Laminating Mandrels Polyurethane and Press Molding.
Adhesives
Each kit contains one 15.2 oz. (450 mL) cartridge set of adhesive, a lock nut and a static mixing wand. The cartridge kits are designed to be used with a Cox PPM-300X manual dispensing gun, a Cox PPA- 300B pneumatic dispensing gun or their equivalent.
Bromine-Free Flame Retardant Resin Systems
Composite Polymer Design offers a variety of flame retardant resin systems. Among them are a series of bromine-free systems that may be used for infusion and injection or hand lay-up that meet or exceed the requirements of UL 94 V0 and FAR 25.853(a) of FAA standards. The CPD 4282A resin was originally developed as a master batch flame retardant dispersion, but may also be used as supplied for bonding, casting and laminating applications.
Wood Laminating Systems
CoPoxy 100A is an epoxy resin that has been specifically formulated for bonding and coating wood. This resin has superb penetrating power, which lends itself to superior moisture resistance and high strength. CoPoxy 100A is available for use with four hardeners of varying work life/gel time. These wood laminating systems are well suited for sealing wood surfaces, bonding applications, general marine construction and repair, and the cold molding process for fabricating wood and fiberglass structures.
Infusion Products
Composite Polymer Design manufactures a variety of epoxy resin systems that are well suited to the infusion process.
Adhesion to Reinforcement
The supreme advantage of epoxy is its excellent adhesion to almost any surface. Epoxy adheres tenaciously to a broad range of substrates, particularly those that are frequently used as reinforcement in composite parts and structures.
- Carbon Fiber - Carbon fiber commonly has an epoxy binder. This binder further promotes the adhesion of epoxy to the substrate and makes an epoxy the ideal resin system for the fabrication of carbon fiber composites.
- Kevlar® – Kevlar® typically does not have a binder. In this case, the superior adhesion characteristics of epoxy make it preferable to other organic polymers for the fabrication of Kevlar® composites.
- Fiber Glass – More so than carbon fiber and Kevlar® composites, fiber glass composites are susceptible to attack by water vapor. Water vapor attacks the interface between resin and reinforcement, and leads to degradation of the composite structure. In the long term, epoxy provides a barrier against water vapor that is superior to other organic polymers and can be used to fabricate more durable fiber glass composites. Fiber glass is available with a wide variety of binders. A number of these binders have been formulated to promote the adhesion of specific organic polymers to fiber glass. As such, it is important to select a grade of fiber glass with an epoxy compatible binder when using an epoxy resin system to construct fiber glass composites.
- Core Material - Where core material has been incorporated into the design of a laminate to produce a light weight composite structure, using an epoxy resin system can provide further weight savings. The superior adhesion characteristics of epoxy eliminate the need for a resin rich mat between the structural reinforcement and the core material.
Versatility
Epoxy resin systems can be formulated with various curing agents, diluents, fillers and other additives to produce an almost unlimited range of properties. The tremendous versatility of epoxy makes it possible to tailor the handling and mechanical properties of an epoxy resin system to what is needed.
Low Shrinkage
Epoxy resin systems exhibit little shrinkage during cure and allow for the precise reproduction of mold surfaces. The dimensional stability provided by an epoxy resin system gives rise to the fabrication of composite parts and structures with lower ingrained stress levels. As a result, finished pieces are stronger and more durable than those produced using organic polymers that exhibit higher values of shrinkage.
Chemical Resistance
Properly cured epoxy resin systems have excellent chemical resistance to acids, bases and solvents. In contrast to other organic polymers, epoxy resin systems are particularly resistant to caustic substances.
No Volatile Loss
Epoxy resin systems formulated for the fabrication of structural composites are typically 100 percent solids. No byproducts, volatile or otherwise, are formed as these systems polymerize. By and large, there are no VOC issues associated with the handling of epoxy resin systems.
